Complete VRT Guide — Vehicle Registration Tax in Ireland

What is Vehicle Registration Tax (VRT)?

Vehicle Registration Tax, or VRT, is a compulsory tax that every vehicle owner in Ireland has to pay before their vehicle can be registered and driven on Irish roads. Whether you buy a brand-new car from a dealer in Dublin, import a used one from the UK, or bring a car in from anywhere else, VRT applies. Revenue collects it, and it's one of the biggest costs you'll face when you own or import a vehicle here.

The tax exists because the Government uses it as a lever for environmental and transport policy. Dirtier cars attract higher rates; cleaner and zero-emission cars get reduced rates or exemptions. The whole setup nudges people toward greener vehicles and away from older, more polluting ones. Knowing how VRT works matters if you're buying, selling, or importing a car — get it wrong and you could be hit with unexpected bills, penalties, or delays getting the thing on the road.

VRT is separate from motor tax, which is the annual road licence fee. You must pay VRT once when you first register the vehicle, and then motor tax every year to keep it road-legal. The two charges are calculated differently and serve different purposes. VRT is a registration charge linked to the vehicle's market value and emissions profile at the point of entry into the Irish vehicle fleet. Motor tax is an ongoing annual charge that also takes CO₂ emissions into account but uses different bands and rates.

Who Pays VRT?

Anyone who brings a vehicle into Ireland from abroad — whether from the UK, Northern Ireland, mainland Europe, or further afield — must pay VRT before the vehicle can be registered. If you buy a vehicle that is already registered in Ireland, the VRT has already been paid by the previous owner, so you do not need to pay it again. However, if you import a used vehicle from the UK or the EU, even if you personally have owned it for years, Revenue will require you to pay VRT on it. There is no blanket exemption for personal imports, and the duty applies regardless of the vehicle's age or condition.

New vehicles purchased from Irish dealers already have VRT included in the price or paid by the dealer before registration. In that scenario, you do not deal with VRT directly. The exception is if you order a new vehicle from a manufacturer and import it yourself — in that case, you become the importer and are responsible for paying VRT.

When Must VRT Be Paid?

VRT must be paid within one calendar month of the date the vehicle arrives in Ireland, or before the vehicle is first used on Irish roads, whichever comes first. If you bring a car into Ireland and start driving it immediately without paying VRT, you are committing an offence and can face fines and penalties. Revenue enforces this strictly, and vehicles caught on Irish roads without proper VRT payment and registration can be seized. The payment deadline is firm, and while extensions can sometimes be granted in exceptional circumstances, they are not automatic.

How is VRT Calculated in Ireland?

Working out VRT pulls a few things together. You start with the Open Market Selling Price — roughly what the car would fetch on the Irish market — and multiply it by the percentage rate for its CO₂ band. Diesel cars get a NOx levy on top. Cars over a year old get an age reduction. Then any relief, like the electric vehicle relief, is knocked off the total. The formula looks simple enough, but each part has its own rules, and they can make a real difference to the final bill.

The VRT Formula

Step 1: Determine the OMSP

The Open Market Selling Price is the foundation of the entire calculation. OMSP is defined as the price a vehicle would fetch if sold in Ireland under normal conditions, including all taxes and duties. Revenue uses this definition because it wants to tax the vehicle at its Irish market value, not its foreign purchase price. This means you cannot simply declare the price you paid in the UK or Germany. Revenue may assess the OMSP independently using dealer prices, valuation guides, and market data. If they believe your declared OMSP is too low, they will issue a reassessment and you may owe additional VRT plus interest and potential penalties.

For new vehicles, the OMSP is generally the recommended retail price in Ireland. For used vehicles, it is the price at which a dealer would sell a comparable vehicle of the same make, model, age, mileage, and condition. You can use the Revenue OMSP tool or consult dealer listings to get an estimate, but Revenue has the final say. Our OMSP calculator can help you determine a defensible OMSP figure.

Step 2: Identify the CO₂ Emissions Band

Your vehicle's CO₂ emissions, measured in grams per kilometre, determine which VRT band it falls into. CO₂ figures are taken from the vehicle's Certificate of Conformity or the National Car Test (NCT) documentation. If no official Irish or EU CO₂ figure is available, Revenue may assign a figure based on engine capacity and fuel type. The bands range from Band A for zero-emission vehicles (0g/km) up through progressively higher bands for more polluting vehicles. The full band table is published by Revenue and updated periodically as emissions thresholds change.

Step 3: Apply the VRT Percentage Rate

Each CO₂ band carries a specific percentage rate. For example, Band A vehicles (0-50 g/km CO₂) pay 7% VRT on the OMSP, while the highest band (191g/km or above) pays 41%. The percentage is applied to the full OMSP of the vehicle. So if your car has an OMSP of €30,000 and falls into Band K (121-125g/km), your base VRT would be €30,000 × 16.75% = €5,025. These percentages have been increased over the years as part of Ireland's climate action strategy, with the aim of making higher-emitting vehicles progressively more expensive to register.

Step 4: Add the NOx Levy (Diesel Vehicles Only)

If your vehicle is diesel-powered, a NOx levy is added to the VRT amount. This levy is calculated based on the vehicle's nitrogen oxide emissions, measured in milligrams per kilometre. The NOx levy was introduced in 2020 as a supplementary charge to address air quality concerns, particularly in urban areas. The levy is capped at €4,800 for passenger cars and varies by vehicle category. Petrol, hybrid, and electric vehicles are exempt from the NOx levy. The exact amount depends on the NOx figure in the vehicle's type approval documentation.

Step 5: Apply the Age Reduction Factor

If the vehicle is more than one year old, an age reduction factor is applied to the base VRT amount (before adding the NOx levy). This recognises that the vehicle has already depreciated and its effective emissions have already contributed to the environment for some time. The reduction increases with the vehicle's age, up to a maximum of 50% for vehicles six years or older. The exact reduction percentages change periodically, so always check the current Revenue table. The age is calculated from the date of first registration, not the date of manufacture.

Step 6: Subtract Any Applicable Reliefs

Finally, if you qualify for any VRT relief — such as the electric vehicle relief, returning emigrant relief, or disabled drivers relief — this amount is deducted from the total. The electric vehicle relief is the most common, offering up to €5,000 off the VRT for battery electric vehicles. Reliefs have specific eligibility criteria and must be applied for at the time of registration. You cannot claim a relief after the fact.

VRT Bands and Rates 2026 — Full Table

The following table shows the current VRT bands and rates for private cars in Ireland as of 2026. Rates are applied as a percentage of the vehicle's Open Market Selling Price. The bands are determined by CO₂ emissions measured in grams per kilometre. These rates apply to cars registered on or after 1 January 2021; vehicles registered before that date may have different band thresholds. Always confirm the current rates with Revenue or use a trusted VRT calculator to get an accurate estimate.

Age Reduction Factors

For vehicles over one year old, the following age reduction factors are applied to the base VRT amount before adding the NOx levy:

These age reductions apply to the base VRT charge. The NOx levy for diesel vehicles is not reduced by the age factor and is calculated separately. This means a five-year-old diesel car will still attract the full NOx levy even though the base VRT is reduced by 40%. Understanding this distinction is important because it notably affects the total cost of registering an older diesel vehicle.

Other Vehicle Category Rates

Commercial vehicles, motorcycles, and other vehicle categories use different rate structures. Commercial vehicles (such as vans and trucks above certain weight thresholds) are generally taxed at a flat rate of 13.3% of OMSP, regardless of CO₂ emissions. Motorcycles are taxed based on engine capacity, with lighter rates that increase with engine size. Category L vehicles (mopeds, light quadricycles, and similar) have their own simplified rate structures. If you are registering a vehicle that is not a standard private car, check the specific Revenue guidance for your vehicle category.

Understanding the Open Market Selling Price (OMSP)

The Open Market Selling Price is the single most important number in any VRT calculation because it determines the base on which all rates are applied. OMSP is defined as the price at which a vehicle would be sold in the open market in Ireland under normal conditions, including all applicable taxes. It is not the price you paid for the vehicle abroad, and it is not the replacement cost of a new vehicle. It is the realistic selling price of that specific used vehicle in the Irish market as if it were being sold through a dealer.

Revenue takes OMSP seriously because it is the primary control against undervaluation. Some importers attempt to declare a low purchase price to reduce their VRT bill, but Revenue cross-references declared values against dealer price lists, online listings, auction data, and valuation guides. If Revenue believes the OMSP you have declared is too low, they will issue a reassessment, and you will owe the additional tax plus interest at 0.0219% per day (approximately 8% per year). In cases of deliberate undervaluation, penalties of up to 100% of the underpaid tax can apply.

How to Determine OMSP

There are several reliable ways to establish a defensible OMSP figure. The most straightforward is to check the prices charged by Irish dealers for vehicles of the same make, model, year, and similar mileage. Online platforms such as DoneDeal, Carzone, and manufacturer-approved used car programmes provide current market data. Revenue also publishes its own OMSP tool on the Revenue Online Service (ROS), which provides indicative values based on make, model, and specifications. While the Revenue OMSP tool is not binding, it gives you a clear indication of what Revenue considers a reasonable value.

If you are importing a vehicle that is not commonly sold in Ireland — for example, a specialist import or a model not officially distributed here — you may need to provide evidence of value from the country of origin. Revenue may accept dealer quotes, auction results, or independent valuations. The key is to be able to justify your declared OMSP with documentary evidence if challenged. Our OMSP calculator helps you estimate your vehicle's OMSP using current Irish market data.

The NOx Levy Explained

The Nitrogen Oxide (NOx) levy is an additional charge that applies specifically to diesel vehicles when they are registered in Ireland. Introduced in Budget 2020, the NOx levy was designed to address the air quality problems caused by diesel exhaust emissions, particularly nitrogen dioxide (NO₂) which contributes to smog and respiratory health issues in urban areas. The levy is calculated separately from the main VRT charge and is based on the vehicle's NOx emissions measured in milligrams per kilometre (mg/km).

The NOx levy applies to all diesel-powered vehicles regardless of age, meaning even a five-year-old diesel car that benefits from a 40% age reduction on its base VRT will still pay the full NOx levy. This is an important distinction that many people overlook when estimating the cost of importing a diesel vehicle. Petrol vehicles, hybrid vehicles, and fully electric vehicles are completely exempt from the NOx levy. The levy amount is capped at different levels depending on the vehicle category: for passenger cars the maximum NOx levy is €4,800, while other vehicle categories have different caps.

How the NOx Levy is Calculated

The NOx levy is calculated using a formula that considers the vehicle's NOx emissions in mg/km. The formula creates a sliding scale where cleaner diesel vehicles (those with lower NOx output) pay less, while dirtier vehicles pay more, up to the cap. Euro 6 diesel vehicles typically have lower NOx figures and therefore lower levies, while older Euro 5 or Euro 4 diesel vehicles attract notably higher charges. The NOx figure is taken from the vehicle's Certificate of Conformity or type approval documentation. If no official figure is available, Revenue may apply a default value based on the vehicle's engine size and Euro standard.

For anyone considering importing a diesel vehicle, the NOx levy is a critical factor in the total cost calculation. A vehicle that appears cheap to import based on VRT alone may become expensive once the NOx levy is added. Use our NOx calculator to determine the exact levy for your specific vehicle before you commit to an import purchase. This can save you thousands of euro and help you make an informed decision about which vehicle to import.

VRT by Vehicle Type

VRT rules differ depending on the type of vehicle you are registering. Private cars use the CO₂-based band system described above, but other vehicle categories follow different structures. Understanding which rules apply to your specific vehicle is essential because applying the wrong rate can result in either overpaying or underpaying, and underpayment attracts penalties.

Private Cars

Private cars — vehicles designed to carry no more than eight passengers plus the driver — are taxed on a CO₂ emissions basis using the band system outlined in the rates table above. This is the most common category and covers the vast majority of vehicles imported into Ireland. The calculation uses the OMSP, the CO₂ band rate, the NOx levy for diesel, age reduction, and any applicable reliefs.

Commercial Vehicles

Commercial vehicles including vans, trucks, and certain minibuses are taxed at a flat rate of 13.3% of their Open Market Selling Price. This rate does not vary by CO₂ emissions. The definition of a commercial vehicle for VRT purposes depends on the vehicle's design and gross vehicle weight. A vehicle that is designed primarily for carrying goods or passengers for hire may qualify as commercial, but Revenue scrutinises these classifications carefully. If you import a van that Revenue reclassifies as a private vehicle — for example, a panel van with rear seats added — you may be charged the higher car rate instead.

Motorcycles

Motorcycles are taxed based on engine capacity rather than CO₂ emissions. The rates are generally lower than for cars because motorcycles produce fewer emissions. Category L2e vehicles (light motorcycles up to 45cc) pay a flat rate of €50. Category L3e vehicles (larger motorcycles) pay approximately €1 to €2 per cc of engine capacity, with the rate varying based on engine size. A 600cc motorcycle would cost roughly €600 to €1,200 in VRT, notably less than a car of equivalent value.

Vans and Light Commercial Vehicles

Light commercial vehicles — commonly known as vans — follow the commercial vehicle rate of 13.3% of OMSP, provided they meet the design criteria for commercial classification. Revenue will look at whether the vehicle is designed and constructed for the conveyance of goods rather than passengers. A vehicle with windows in the rear, seats for passengers, or domestic-style fittings is more likely to be classified as a private car. If you are importing a vehicle that could fall into either category, check with Revenue before paying VRT to ensure you are paying the correct rate.

Electric Vehicle VRT Relief — What You Need to Know

Ireland offers notable VRT relief for electric vehicles as part of the Government's climate action strategy to accelerate the transition away from fossil fuels in transport. The relief is designed to make electric vehicles more affordable and encourage drivers to switch from petrol and diesel. Understanding the full details of this relief can save you thousands of euro when registering an electric vehicle in Ireland.

Battery Electric Vehicle (BEV) Relief

Battery Electric Vehicles — vehicles powered entirely by an electric motor with no internal combustion engine — qualify for the most generous VRT relief. As of 2026, the maximum relief for a new BEV is up to €5,000. This relief is applied as a direct deduction from the calculated VRT amount, meaning it reduces the tax you owe on euro-for-euro basis. For a new electric car that already falls into the lowest 7% VRT band due to zero CO₂ emissions, the relief is effectively redundant because the base VRT is already low. However, for used BEVs imported into Ireland, the relief is extremely valuable because the vehicle may fall into a higher CO₂ band based on its age when first registered, or the relief may apply differently depending on when it was first registered and its age at the time of import.

Plug-in Hybrid Electric Vehicle (PHEV) Relief — Ended 31 December 2021

Plug-in hybrid VRT relief used to exist, but it ended on 31 December 2021. PHEVs now pay the standard CO₂-based VRT rate for their emissions, with no preferential relief. If you're weighing up a PHEV, budget for the full VRT — you can't rely on any hybrid discount. Battery electric vehicles are the only ones that still get the relief described above.

Eligibility Criteria

To qualify for EV VRT relief, the vehicle must be a new or used vehicle that is being registered in Ireland for the first time or being re-registered after a period of deregistration. The vehicle must meet the definition of a BEV or PHEV under Revenue's rules. There are also price caps — vehicles above a certain price may receive reduced or no relief. The number of vehicles eligible for relief each year is monitored, and the scheme is subject to periodic review. Always check the current Revenue guidance before relying on EV relief in your VRT calculation, as the terms can change with each Budget.

Importing a Car into Ireland and VRT

Importing a vehicle into Ireland is the most common scenario in which individuals encounter VRT. Whether you are bringing a car from the United Kingdom, purchasing a used vehicle from a German dealer, or importing a classic car from France, the VRT process is the same. The vehicle must be presented to Revenue, the OMSP must be assessed, the appropriate VRT must be paid, and the vehicle must be registered before you can legally drive it on Irish roads.

The process begins before you even bring the vehicle into Ireland. You should research the total cost of importing, including not just the purchase price but also shipping or transport costs, insurance for the journey, any customs duties (which may apply for non-EU imports), VAT on the purchase, and of course the VRT. Many people focus on the UK auction price or dealer price and are shocked when the total landed cost in Ireland — including VRT — exceeds what they would have paid for the same car in Ireland. Always calculate the full cost before committing to a purchase abroad.

UK Imports Post-Brexit

Since the UK left the European Union, importing a vehicle from Great Britain (England, Scotland, Wales) has become more complex. Vehicles from Great Britain are now treated as imports from a non-EU country, which means customs declarations, potential customs duties, and import VAT apply in addition to VRT. Vehicles from Northern Ireland, which remains in the EU customs area under the Windsor Framework, do not attract customs duties but still require VRT payment. The administrative burden of UK imports has increased notably since Brexit, and many importers now choose to source vehicles from EU countries instead to avoid the additional complexity and costs.

Step-by-Step Import Process

1. Purchase the vehicle and obtain all original documentation including the foreign registration certificate, Certificate of Conformity, and proof of purchase.
2. Arrange transport or drive the vehicle into Ireland, ensuring you have valid insurance for the journey.
3. If importing from Great Britain, complete customs declarations and pay any applicable customs duties and import VAT.
4. Present the vehicle to Revenue's VRT division at a designated Motor Tax Office or NCTS centre.
5. Revenue will assess the OMSP, calculate the VRT, and issue a VRT payment demand.
6. Pay the VRT within the required timeframe.
7. Once VRT is paid, the vehicle will be registered and you will receive your Irish registration number.
8. Obtain motor tax and insurance, and your vehicle is ready for the road.

Our Import Car VRT Calculator helps you estimate the total cost of importing a specific vehicle, including VRT, NOx levy, and any applicable reliefs.

VRT Exemptions

While most vehicles registered in Ireland attract VRT, there are several categories of vehicles and situations that qualify for full or partial exemption from the tax. Understanding whether your vehicle qualifies for an exemption can save you a fair amount of money. However, exemptions are narrowly defined and Revenue applies the criteria strictly, so you should not assume an exemption applies without verifying it against the current rules.

Common VRT Exemptions

• Returning Emigrants: Irish citizens or residents returning to Ireland after living abroad for a continuous period of at least 12 months may qualify for a VRT exemption on one vehicle they bring with them, provided the vehicle was owned and used by them abroad for at least 6 months before returning. Strict conditions apply and the exemption must be claimed within 12 months of return.
• Disabled Drivers and Disabled Passengers: Vehicles modified for use by disabled drivers or passengers may qualify for VRT exemption or reduced rates. The vehicle must meet specific modification criteria, and a medical certificate must be obtained. The exemption applies to one vehicle per eligible person.
• Diplomatic Vehicles: Vehicles owned by diplomatic missions, consular posts, or international organisations with diplomatic status may be exempt from VRT under the Vienna Convention on Diplomatic Relations. This exemption does not apply to locally employed staff or honorary consuls.
• Temporary Imports: Vehicles brought into Ireland temporarily — for example, by tourists, visitors, or for short-term use — may be exempt from VRT provided they are not permanently imported and are taken out of Ireland within the permitted period. This typically covers vehicles registered abroad that are being driven in Ireland for up to 12 months.
• Certain Agricultural and Construction Vehicles: Some categories of agricultural and construction vehicles are exempt from VRT under specific provisions, though motor tax and other charges may still apply.

For a comprehensive list of VRT exemptions and detailed eligibility criteria, visit our VRT Exemptions page. Each exemption has specific documentation requirements, time limits, and conditions that must be met. If you believe you qualify for an exemption, gather all required evidence before presenting your vehicle to Revenue.

The VRT Registration Process in Ireland

Registering a vehicle with Revenue involves a structured process that ensures all taxes and documentation are in order before the vehicle receives its Irish registration plate. Whether you are registering a newly imported vehicle or a new vehicle purchased from an Irish dealer, the process follows similar steps. Understanding what to expect can help you prepare the right documents and avoid delays.

Before You Go

Before presenting your vehicle for VRT registration, make sure you have the following documents ready: the foreign registration certificate (or vehicle ownership document), the Certificate of Conformity (which shows the vehicle's emissions specifications including CO₂ and NOx figures), proof of identity (passport or driving licence), proof of address, proof of purchase (invoice or bill of sale), and valid motor insurance for the vehicle. If you are importing from Great Britain, you will also need your customs documentation showing any duties and import VAT paid.

Presenting the Vehicle

You must present the vehicle in person at a designated Motor Tax Office or National Car Testing Service (NCTS) centre. The vehicle will be inspected to verify its identity — the chassis number, engine number, and other identifying features will be checked against the documentation. Revenue officials may also inspect the vehicle's condition and specifications to ensure they match the documentation provided. For most standard vehicles, this process takes a few hours. For unusual or specialist vehicles, it may take longer.

Paying the VRT

Once Revenue is satisfied with the documentation and vehicle inspection, they will issue a VRT payment demand. This will show the calculated VRT amount, any NOx levy, and any reliefs applied. You must pay the full amount before the vehicle can be registered. Payment can be made by debit card, credit card, or bank transfer at the Motor Tax Office. Online payment through ROS is also available for certain categories of importers, particularly motor dealers. Once payment is received, Revenue will register the vehicle and issue your Irish registration number.

After Registration

With VRT paid and the vehicle registered, you can now apply for motor tax (the annual road licence) and obtain motor insurance. You will receive a VRT certificate confirming the registration, which you should keep with your vehicle documents. The registration number will be recorded on the national vehicle register, and the vehicle will appear on the NCT database for future testing purposes.

How to Reduce Your VRT — Practical Tips

There are several legitimate strategies you can use to reduce the amount of VRT you pay when registering a vehicle in Ireland. While you cannot avoid VRT entirely, you can make smarter purchasing decisions and take advantage of available reliefs to minimise the cost. The key is to plan ahead and understand how the VRT calculation works before you commit to buying a vehicle.

Choose a Lower-Emission Vehicle

The most effective way to reduce your VRT is to choose a vehicle with lower CO₂ emissions. Moving from Band 20 (41%) to Band C (15.6%) — for example, by choosing a petrol hybrid instead of a diesel SUV — can save thousands of euro on VRT alone. When shopping for a vehicle, always check the CO₂ emissions figure and use it to calculate the VRT before you buy. Even small differences in CO₂ can push a vehicle into a different band, so the emissions data should be a key factor in your purchasing decision.

Consider an Electric Vehicle

Fully electric vehicles (BEVs) benefit from both a 0% VRT band and up to €5,000 in EV relief. This makes them the cheapest vehicles to register in Ireland from a VRT perspective. If you are considering a new vehicle purchase, an EV can save you between €5,000 and €15,000 or more in VRT compared to an equivalent diesel or petrol car. Plug-in hybrids (PHEVs) no longer receive any VRT relief — their relief ended on 31 December 2021, so PHEVs now pay standard VRT rates based on CO2 emissions.

Factor in the NOx Levy for Diesel Imports

If you are importing a diesel vehicle, always calculate the total cost including the NOx levy before committing to the purchase. A diesel car with a low purchase price but high NOx emissions can end up more expensive than a slightly pricier petrol or hybrid vehicle with a lower total VRT cost. Check the NOx figure on the Certificate of Conformity and use our NOx calculator to estimate the levy.

Declare an Accurate OMSP

While it is tempting to undervalue your vehicle to reduce VRT, this is extremely risky. Revenue routinely reassesses OMSP values and can impose penalties and interest on underpayments. It is far better to declare an accurate OMSP backed by market evidence and focus your savings strategies on the legitimate methods outlined above. If you declare an OMSP that is too low, you may end up paying more in penalties than you would have saved in VRT.

Check for Exemptions and Reliefs

Always check whether you qualify for any VRT exemption or relief before registering your vehicle. If you are a returning emigrant, disabled driver, or qualify for any other specific relief, claiming it at the time of registration can save you thousands. Check our VRT Exemptions page for the full list of available exemptions and eligibility criteria.

VRT Appeals — What to Do If You Disagree

If Revenue issues a VRT assessment that you believe is incorrect — whether because they have used the wrong OMSP, applied the wrong band, miscalculated the NOx levy, or denied a relief you are entitled to — you have the right to appeal. The appeals process is formal and time-limited, so it is important to act quickly and provide comprehensive evidence to support your case.

Internal Review

The first step in challenging a VRT assessment is to request an internal review from Revenue. You must do this within four months of the date of the original assessment. The request should be in writing, clearly state the grounds on which you are appealing, and include any supporting evidence you have. Revenue will review the assessment and issue a decision. This process is free and does not require legal representation, though it is advisable to seek professional advice if the amounts involved are notable.

Tax Appeals Commission

If you disagree with the outcome of Revenue's internal review, you can appeal to the Tax Appeals Commission (TAC). TAC is an independent body that adjudicates disputes between taxpayers and Revenue. You must lodge your appeal within four months of the date of Revenue's internal review decision. The appeal is made by filing a notice of appeal with TAC, and the process may involve an oral hearing where you (or your representative) present your case to an appeals commissioner. TAC decisions can be appealed to the High Court on a point of law.

Grounds for Appeal

Common grounds for VRT appeals include disagreements over the OMSP valuation, disputes about which CO₂ band applies, arguments about the vehicle's age for reduction purposes, challenges to the NOx levy calculation, and claims for reliefs or exemptions that have been denied. To succeed in an appeal, you need to provide clear evidence that Revenue's assessment is wrong — for example, by showing market data that supports a lower OMSP, documentation showing the correct CO₂ figure, or evidence of eligibility for a relief.
